AIR PUMP OR CONDENSER.

' ing or conveying, and compressing or conof the machine, substantially at right angles densing fluids wherein .a' denser fluid or medium is made to compress or condense fluids of lesser. density. 'The' denser fluid flows or is conveyed in any suitable manner to a rotating member of the device. Centrifugal action throws the fluid outward into a surrounding member, and its outward flow is so interrupted that the fluid forms a continuous series of spaced fluid masses which have a piston-like'action onthe less dense fluid. If the denser fluid be water and the less dense fluid be steam, a condensation of the steam will also occur when the two fluids are brought together in the outer member.

-The object of my invention isthe provision of a simple and eflicient device for rforming the operations described, inw 'ch the rotary member has separate channels or conduits for the two fluids, a construction which makes it possible to design each set of channels or conduits to suitthe particular characteristicsof the fluid to be conveyed thereby.

In the accom anying'drawing, showing an illustrative em odiinent of my invention, Figure 1 is a partial sectional View with the plane of the section perpendicular to the axis of the machine; and Fig. 2 is a section through the rotary and stationary members to the plane at the section in Fig. 1.

The rotary member or impeller wheel 1 is mounted upon a'shaft 2 driven in any suitable manner. Surrounding the wheel is. a directing ring or member A casing 4, only a p-ortion of which is shown in the drawing, incloses the mechanism just described, supporting the ring 3,, affording bearingsfor the shaft 2, and roviding suitable channels or conduits fort e entrance of the two and for the exitor discharge of the resultant uid.

Serial No. 853,615.

A conduit 5, for supplying water or other fluid to the wheel 1, is shown in the drawing. This conduit leads to a series of outwardly directed conduits or passages 6 in the irn- The cross-section. of the pa:- sages 6 is gradually reduced from the inlet to the outlet but the shape of said passages may be varied to suit the o crating conditions to The sides of the which also form the faces or sides of the wheel. Extending from one wall 7 to the other are walls or partitions 8 which form, between. them the passages or buckets 6 and. another set of conduits-or passages 9 which alternate with the passages6 around the circumference of the impeller wheel. The walls or blades 8 are grouped in pairs with their ends toward the shaft united to form a sharply defined edge between the entrances to tie passages 6. Beyond this edge, the

walls separate to form the passages or buckets 9. Opcnings lO in the sides of the wheel communicate with the passages 9. The outer ends of the walls 8 are supported by portions 11 of the wheel rim which span the openings 10 but leave a clear outward pas- Curved passages or conduits 12 are formed between the partitions or blades 13 of the directing ring 3. The curvature of these passages is op osite to that of the passages 6. A small 0 earance space 14 is pro vided between the rim of the wheel 1 and the directing ring 3.

As the im el'ler wheell is rotated in the direction of t e arrow, Fig. 1, water or other fluid entering the passages or buckets 6 from the conduit 5 is thrown outward by centrifugal action into the passages or buckets 12, but because of the interruption of the connection between the passages or buckets 6 and 1.2, separated columns or masses of water 15 are formed in the conduits 12. Between these fluid masses 15 are portions of air, steam .or other fluid which are drawn through the openings 10, passages 9 and the space 14, from the space surrounding the wheel and the conduit 5, and are forced outward by the piston-like action of the fluid masses 1.5. The discharge from the passages 12is collected in a suitable. portion of the surrounding casing and is disposed of as desired.

The arrangement described is very efficient and simple, having no valves orreciprocating parts. The moving member has a rotary motion, and is rovided with separate passages for the two uids so that they are efficiently handled and brought together only in the directing member where the compres-' sion or condensation occurs.

In" accordance with the provisions of the patent statutes, I have described the princi- .ple of operation of my invention, together with the apparatus which I consider to represent tloe' best embodiment thereof; but I desire .to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.

What I claim as new and desire to secure by Letters Patent of the United States, is,-

l. The combination of a rotary impeller having se arate sets of fluid discharging passages, wit a casing, a member locatedwithin the casing and surrounding the periphery of the im eller that is provided with passages whic receive fluid first from one set of passages in the impeller and then from another set as the periphery of the impeller moves past the inlet openings of the passages in said member.

2. The combination of a rotary impeller having separate sets of fluid passages arranged in multiple, each set receiving and discharging a different fluid, with astationary casing incl'osing the impeller and having a member provided with passages to which the different fluids discharged from the sets of passages in the impeller are successively delivered to form streams composed of successive masses of said fluids.

3. The combination of an im eller having a set of passages which receive uid near the axis, of the impeller and discharge it outwardly, and a second set of passages which receive fluid from openings arranged in multiple and discharge 1t outwardly, and a mem 'peller being relatively rotatable. .5. The combination of a rotatable impeller, a fluid-supply conduit adjacent the center of the impeller, conduits in the impeller leading from the supply conduit to openings in the circumference o the impeller,

other and separate conduits in the impeller leading from a separate source of fluid-supply to separateopenlngs in the circumference of the impeller which alternate with the first set of openings, a directing member adjacent the impeller circumference, and conduits in said member which receive the fluid dis-. charged by centrifugal action from the openings or outlets in the circumference of said impeller.

6. The combination of an impeller rovided with .a series of alternating con uits leading from separate inlets in its hub and face respectively to se arate outlets in its circumference, with a irecting ring concentric with the impeller, conduits in the ring, and means for rotating the impeller to interrupt the delivery of fluid from the outlets to the conduits in the ring.

7. The combination of an impeller, a sup-' ply conduit adjacent the center of the 1m- .peller, a series of conduits leading from the supply conduit to the circumference of the impeller, a separate series of conduits between the openings in the face of the impeller and openings in its circumference, a directing ring adjacent the circumference of the impeller, and a series of conduits in the ring cooperating with the impeller conduits,

the impeller and the ring being relatively rotatable. w

. 8. The combination of an impeller, a series of inlets adjacent the center of the impeller, a series of inlets in the face of the impeller, alternating series of outlets in the impeller circumference, a separate series of conduits joining each series of inlets with one of the series of outlets, a directing member surrounding the impeller, and a set of conduits in the member cooperating with the outlets in the impeller circumference, the impeller and the memberbeing relatively rotatable.

9. Thecombination of an impeller, conduits extending from adjacent the center of the impeller to its periphery, zwalls for said conduits extending transversely to lateral faces ofimpeller, conduits formed in said walls which lead from openings in the face of the'impeller to outlets in its periphery, and a directing member surroundlng the impeller.

10. The combination of a shaft, an 1mpeller wheel having a hub mounted on the shaft, an annular flange projecting parallel to the shaft from one sideof the hub and having a series of openings on the inside thereof, two spaced circular flanges on the periphery of the first flange substantially at right angles to the axis of the shaft, conduits leading from said openings tooutlets in the .clrcumference of the impeller, said conduits being formed by walls extending across the space between the two flanges, condults formed in said walls. which lead from inlet openings in the outer faces of the flanges to outlets in the circumference of'the impeller that alternate with the outlets of the first series of conduits, and a directing member surrounding the impeller having conduits which receive the discharge from the conduits in the impeller.

In witness whereof, I havehereunto set my hand this 5th day of January, 1907.
